Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention mainly relates to a water surface floating object collection method that floats on the water surface of a household bathtub or the like and automatically and highly efficiently collects and removes water surface floating objects such as dirt and hair loss. Regarding equipment.

[Conventional technology]

The present invention is disclosed in Japanese Patent No. 1037522 (Japanese Patent Publication No. 55-25887).
The present invention relates to an improvement of the water surface floating object collecting device according to No. 1), and first, the water surface floating object collecting device of the original invention will be explained based on FIG. 3.

When the water surface floating object collection device is floated on the water surface,
The floating container 1 of the device floats with its lower half submerged in water, and water rapidly flows in from the entire opening of the inlet 2 submerged under the water surface, is filtered by the filter member 3, and the floating container 1 floats.
The water instantly accumulates in the water reservoir 4 on the opposite side beyond the line of action F of the buoyant force near the center of the water. When the water reservoir 4 sinks further due to the weight of this accumulated water, the inlet 2 on the opposite side with the line of action F of buoyancy in between rises in the water, and the upper part comes out from the water surface, preventing the inflow of water. This restricts the flow of surface water.

On the other hand, the accumulated water in the water reservoir section 4 is rapidly drained out of the floating container 1 by a powered drainage means 6 such as an electric water pump operated by a battery 5, so that as the accumulated water decreases, the water reservoir section 4 is When it rises rapidly in the water, the inlet 2 sinks a little and the inflow increases, and when the amount of drainage and inflow are balanced, the floating container 1 becomes almost stationary, and the surface water flows out from the inlet 2. Flow in smoothly.

This relationship between the inlet 2 and the water reservoir 4 is such that when the accumulated water increases and the water reservoir 4 sinks, the inlet 2 on the opposite side of the line of action F of buoyancy rises, increasing the amount of inflow water. conversely, when the pooled water decreases and the water reservoir 4 rises, the inlet 2 sinks and increases the amount of granular water, adjusting the inflow to the same amount as the discharge, but this is due to the potential see-saw action. The water level in the water reservoir 4 is always kept below the water level outside the floating container 1 by a certain value, and the water level difference between the two water levels inside and outside the floating container 1, that is, the head, is always approximately constant. Retained.

Therefore, during highly efficient collection of floating objects on the water surface, the floating container 1 is in a nearly stationary state, and the surface water flows smoothly into the inlet 2, so that the surface water is limited to the surface water where the continuity of the liquid is maximized. At the same time, since it flows in with a head difference, in the case of a bathtub water surface where most of the floating matter such as dirt is floating on the water surface, it is possible to quickly and efficiently attract and collect floating matter from the entire surface, so that the floating matter can be quickly and efficiently collected. This is a water surface floating matter collection device that can be extremely effective in purifying water.

[Problem to be solved by the invention]

The water surface floating object collecting device according to the above patent No. 1037522 has a remarkable water surface purification function as described above, but when it is floating on the water surface and collecting water surface floating objects, something happens. This causes large waves on the water surface. Or, when taking a bath, you are submerged in a bathtub, the collection device is floating, and you suddenly stand up. Or,
If an excessive amount of water flows into the floating container, such as by intentionally pushing the collection device into the water, the collection device will sink just like any other ship.

Furthermore, even if the collection device avoids sinking, once excessive water enters the floating container and it becomes semi-submerged, the floating container 1 will rise to the water surface again and the power drainage device will drain the accumulated water. Even though water was drained and water appeared to continue flowing in from the inlet, it was not possible to attract and collect floating objects floating on the external water surface.

This is because if too much water flows into the floating container and the water levels inside and outside the floating container become the same water level, the water on the water surface will no longer flow into the inlet, and the highly efficient collection function of floating objects on the water surface will disappear. Since it did not recover, there was a problem in that the water in the floating container had to be discarded and then floated again.

Even if water exceeding the allowable amount flows into the floating container and the water level difference between the two water levels inside and outside the floating container disappears, the disappeared water level difference can be easily restored, and the head difference between the two water levels can be restored. The object of the present invention is to obtain a water surface floating object collection device that can restore a highly efficient collection function of water surface floating objects.

[Means to solve the problem]

In order to achieve the above object, the water surface floating matter collection device of the invention includes a floating container having a water inlet and a water reservoir for storing inflow water flowing from the inlet, and a water reservoir in which the water is collected. A powered drainage means is provided for forcibly discharging the ivy water to the outside, and a filtration member for filtering the inflow water is provided in the water flow path, and the inlet and the water reservoir are connected to the floating container. A pair of underwater buoyant bodies are located on opposite sides of each other with the line of action of buoyancy in between, and are provided on both sides of the flow path between the inlet and the water reservoir 4.

[Effect]

When the water surface floating object collecting device configured as described above is floated on the water surface and water surface floating objects are collected, if for some reason excessive water flows into the floating container, the water reservoir section will settle abnormally, but the inlet The flow path up to the water reservoir is buoyant by a pair of underwater buoyant bodies on the left and right, so the inlet pops out above the water surface, causing the floating container to be in an extremely forward tilted state, and in extreme cases, to be inverted. However, the inflow of water is interrupted and the ship does not sink.

On the other hand, since the standing water is being drained by a powered drainage means, as the water collecting section that is abnormally submerged in the water rapidly rises to the surface, the inlet that was above the water surface descends and returns to the water surface. The surface water flow resumes and the floating container assumes its normal collection position.
An amount of surface water equal to the amount of water discharged by the powered drainage means is
The water flows smoothly through the inlet, and the ability to collect floating objects on the water surface is restored.

In addition, if you forcefully push the floating container 1 into the water,
The buoyant force of the underwater buoyant body resists the pushing force, making it difficult to keep the floating container depressed for a long time, and when you release your hand, it immediately rises to the surface of the water and returns to its normal smooth inflow state for a while.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings. In FIGS. 1 and 2, a floating container 1 of a water surface floating matter collection device collects water that flows in from an inlet 2 and is filtered by a filter member 3. It has a water reservoir section 4 for storing water, and is provided with a powered drainage means 6 such as an electric water pump operated by a battery 5 for forcibly discharging the water accumulated in the water reservoir section 4 to the outside.

A buoyancy material such as styrofoam, a hollow body containing a gas such as air, or A pair of underwater buoyant bodies 8 and 8', such as container-shaped bodies with open tops, are provided side by side to ensure the underwater buoyancy of the channel section 7 of the floating container 1.

In addition, when the collection device is used for a purpose of use, for example, a collection device for a home bath, the lower part of the center of the floating container 1 and the upper tip of the water reservoir 4 should be Auxiliary underwater buoyant bodies 9, 9' of any shape are connected to or integrally attached to the underwater buoyant bodies 8, 8' on the diagonally upper part of the connection, and further, depending on the shape of the floating container 1 or as necessary. Accordingly, the unnecessary space of the floating container 1 is filled with the underwater buoyancy body, etc., and the underwater buoyancy is enhanced.

The inlet 2 when collecting floating objects on the water surface is located at a water surface position where it can capture the water surface line, allow the external water surface to flow smoothly into the inlet 2, and attract and collect surface water with high efficiency. Since the underwater buoyancy on the inlet 2 side is weaker than the underwater buoyancy in the water reservoir 4 and is uncertain, if necessary, an arbitrary shape can be formed on the back of the bottom of the channel section 7 near the inlet 2. It is also possible to provide an underwater buoyant body to provide the inherent buoyancy on the inlet 2 side.

Furthermore, in the case of a collection device for a home bath, the weight load is reduced especially near the inlet 2 of the floating container 1, and the weight is distributed so that the inlet 2 can easily pop out above the water surface when an excessive amount of water flows in. It is a good idea to have a configuration that

[Effects of the Invention] Since the present invention is configured as described above, it produces the effects described below.

By providing a pair of underwater buoyancy bodies on both sides of the flow path of the floating container, excessive water flows into the floating container, the water level difference between the two water surfaces inside and outside the floating container disappears, and the function of collecting floating objects on the water surface also disappears. When this happens, the flow of water into the floating container is suppressed for a while, the water level difference between the two water surfaces that disappeared is restored, and the external surface water flows smoothly into the floating container again with a head difference. You can definitely restore the function of attracting and collecting floating objects on the water surface.
